antenna amplifier

Model:UA-845   Guangzhou Jodie Audio Equipment Co., Ltd.

The main unit is equipped with an independent cascading port. Among the 5 units, all 5 units have cascading ports that can be used normally for connecting the microphone main unit. If there are more than 5 microphone units, they can be connected to the next antenna amplifier main unit through the cascading ports to receive all microphone signals from two antenna elements. The theoretical number of cascading ports for the antenna amplifier main unit is not limited. A multi-channel system is provided for using 5 UHF wireless series or other series of various automatic selective receivers, sharing one pair of antennas. This is to simplify the antenna assembly process, improve the reception distance and efficiency. The latest design with active elements and active feedback constant current bias has ultra-low internal distortion characteristics, which can eliminate frequency mixing interference when used in multiple channels simultaneously. The output gain is approximately 1. The antenna input socket can directly be configured with various single-pole antennas, coaxial antennas, extension antenna groups, and log directional antenna groups within the applicable frequency band range. The antenna input connector provides power supply for the power amplifier, and can directly connect the extension antenna group with an antenna power amplifier or the log directional antenna group with an internal antenna power amplifier. Four power output options: 12V/600~1000mA. The antenna amplifier main unit provides 220V output, which can be connected to the next antenna amplifier main unit or other 220V electrical appliances.
